Application Ilcd November 22, 1913. Serial No. 302,387.

To ciZZ whom it may concern Beit known that l, lViLhniM C. Brasilia, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new anduseful Improvements in iFuel Saving Devices, of which the following is a specification.

The present invention relates to new and useful improvements in fuel saving apparatuses as described in my (io-pending application, Serial No. 799,044, tiled November 3, isis. j l

The invention has for an object to provide means for supporting and retaining the air preheating chamber within the sinolic tiue which will greatly reduce the cost of manufacture of such devices and at the same time present a strong and eficient Structure which will render the device commercially del fore niixincr with Athe combusti le gases arisingrr fromt etuel. n The above and other objects willbe. more readily apparent to those skilled within the art whentalcen in connection with the 'ollowing' detailed description and the structure 'shown in the drawings which consist of the novel 'features of construction, conibination and arrangement of parts as will be hereinafter particularly pointed out in the appended claims.

in the drz'iwinfsz-elligure 1 is a side ole viition of the stove pipe embodying .my iiiveiitiou. Fig. 2 is a vertical sect-ion through saine, and Fig. is a horizontal section.

reference now being had to the accompanying' drawings 'wherein like and corresponding parte are dsiignated, by siii'iiiai`l reference ciuiructcrs tliri'iughl'iiit the several views, thenunieral 'l indicates a eyliiidrii'xal casing having supported therein an air proheating chamber 2., Secured to the loi-yer cud ofthe casini;r 1. by a beaded connection is an inverted conical section il having so cured to its lower extremity by means of a beaded connection a cylindrical section Il. lhe plate 5 'is connected to the upper end ot' the casing l by means ci the beaded connecc tions as shown and secured to the plate 5 is a cylindrical section 6, being of the same diameter as section t. A damper 7 caxzried by shaft 8 journaled within the section' is adapted to be operated by a handle 9 in the usual manner. Leading to the upper end of the section 6 is an overdraft opening 10 having a. door l1 hingedly sediired thereto whereby the overdraft leading' to the device ma be suitably controlled.

he structure herein described is adapted to form one section of an ordinary stove pipe and the sections 4 and 6 thereofbeing adapted to be connected t0 the adjacent Sec'- tions of the stove pipe are of the eamediameter as the stove pipe to form a continuation thereof.

Whereas this device is shown as being a section of. an ordinary 4stove pipe, it is, of course, to be understood that the same may be placed within a flue or chimney with the same satisfactory results.

The air pre-heating chamber 2 comprises a, cylindrical tube 1Q which is of less exteiiordiametcr than the interior diameter of the outer casing thereby forming Ya passage way ll there between. Secured to thc lower end ot' the tube l2 by means of the beaded connection 14 is an inverted conical section 1 5, having a plurality of Openings 16 formed therein .for a purpose which will be later descxribed. The up ier end of the tube 12 is closed by means oi the wall 17. For supporting the tube 12 within the casing 1 i have provided a plurality of tubes 18 which are iii communication with the cham bei' and the atmospheric air whereby a suitable air supply will he directed to the air preheatinig chamber 2. To retard the air as it enters the air pre-heating chamber 2 I provide adjapcnt the openings which are in coiiuiiui'iicatioii with-the tubes 18 baille platos'lil which are suitably .secured to the inner periphery oi? the tube l2 by any suitable means: or hy rivets 20 as shown.

Viii-the opta. is permitted to enter the tubesld 'in the direetions oi the arrows as shown where it.

enters. the chamber if), the air passing down the cliaiiib'cr i? will tlicii iiecoiiie heated by hot rases arising from the coiiil'iustioii of the fuel and subsequently passing through Patented Oct. 27, 1914.
